The rise of nanometers

Haifeng County Data Center of Time Information.

The freshly baked Glass Dragon 1, as well as the supporting recorder, reader, and storage cabinet, were installed in the cold standby database by Dragon Totem's technicians.

As interns, Wang Zhiyuan, Lu Qifu and others were also dispatched to participate in the construction of the cold standby database.

"Zhiyuan, test the data reading."

"OK."

Data storage cabinets are designed specifically with ease of reading in mind.

Specially designed optical disc display trays. Each display tray can fix an area of ​​25 Glass Dragon 1 glass discs. These display trays can be inserted into data storage cabinets after fixing the glass discs.

A data storage cabinet has a length of 6.4 meters, a width of 0.64 meters, and a height of 1.8 meters. It has 40 floors in total. It can arrange 400 display plates, 10,000 glass dragon 1 glass discs, and can store 89,800 TB of data.

Currently, the database of the National Library only stores about 20T of data.

In other words, the storage capacity of a data storage cabinet is equivalent to 4,500 National Library databases.

After the glass disc in the data storage cabinet is inserted, there is no need to take it out if you want to read the information.

Because each floor of the data storage cabinet is equipped with 10 fast readers, the data in the corresponding area can be directly read through the computer at the main console.

Wang Zhiyuan used the internal laptop and the inserted test display disk to quickly retrieve the data.

In the retrieval catalog system designed by Time Information, the position of each display disk and the position of the reader will affect the reading speed.

Generally, the fastest is about 0.3 seconds, and the slowest is about 6 to 7 seconds.

This speed is incredibly fast for cold backup.

Wang Zhiyuan, who was checking the test data, saw the huge storage capacity and incredible reading speed for the first time. His hands typing on the keyboard could not help but tremble slightly.

"Team Leader Li, there is no problem with storage level 16."

"Test the 17th floor."

"OK."

Not far away, Lu Qifu, who was working with a software engineer, had a huge impact on his outlook.

They are trying to transfer the data from the tape disk to a glass optical disk. The recording speed of the 12-channel deep ultraviolet recorder can record 33 to 50G per minute. This speed can only be said to be relatively good.

Time Blog has been online for more than a year, and there is a lot of data backed up in the database. So far, there are 72.41 million registered users of Time Blog, and 340,000 group accounts.

All the data generated by each account is stored in the database by Time Blog. Even if the data generated by each account is not much, there are 72.75 million accounts after all.

In addition, later blogs, social circles, cloud checks, mailboxes, Time Friends, cloud malls, application stores, legal aid, charity homes, industrial software platforms, Time Chinese Network, and Time Wallet were added.

The basic Internet ecology of Time Information has developed into a very comprehensive and almost self-contained system.

Even in some aspects, Time Information can become the leader in the industry. Even if it is Taotao.com, their payment platform is not necessarily more comprehensive and convenient than Time Wallet.

For example, Time Wallet allows you to directly query the phone bill balance, bank card balance, credit card arrears, and some tap water arrears of communication operators in the city service of Time Blog. Taotao.com cannot do this at this stage.

The emergence of these Internet services has also resulted in the data center of Time Information needing to store more data and withstand greater data access.

There is another problem, that is, with the growth of time information, many friends, both at home and abroad, want to destroy time information.

Since the launch of Time Blog, it has been attacked by hackers for a long time. Time Information’s firewall and network security team are basically preparing for war around the clock.

The birth of Lilong 1, in a sense, has strengthened the information security of Time Information, because the powerful and complete backup can ensure that Time Information has the trump card to restart.

Even if the entire network collapses completely, Time Information can rely on the backup data to reset all user information and set the time back to the latest time point in the backup.

Especially for Time Wallet, the emergence of Glass Dragon 1 has improved the security of user assets. Compared with data stored in a hard disk, it is easier to be modified by hackers. The non-modifiable characteristics of glass discs are basically at a disadvantage. No solution state.

Time Information is already planning to build a capital account data storage center. This capital account data center will have three cold backup databases and three dynamic databases.

The dynamic database is connected to the network and directly connected to the payment backend of Time Wallet. It also cooperates with the fund monitoring team to ensure the safety of users' funds.

At the beginning of the design of Time Wallet, a rule was set, that is, during the transfer process, after the funds arrive, there will be a thirty-minute freezing time for the transferred funds.

To be exempted from this freezing time, unless it is between related family accounts, between official institutions, or between internal company accounts, only this type of fund transactions can be exempted from the freezing time.

If it is between strangers, there is no way to exempt the half-hour freezing time.

If you want to commit fraud through Time Wallet, you will have to face a half-hour fund freezing time. Moreover, due to the real-name registration system, if you commit illegal activities, once it is confirmed that there is an illegal act, all the accounts associated with your name will be directly blocked. freeze.

At the same time, Time Wallet does not support overseas fund transactions. To transfer funds to bank cards, you can only choose domestic bank accounts.

These designs reduce online telecommunications fraud and increase the difficulty of operation.

The first data storage cabinet currently built is used to store blog user information.

Five recorders worked at the same time and could record 150-250G per minute. Lu Qifu and others were busy for two hours and successfully migrated 23,000G of data to the glass disc, which is equivalent to storing a database of the National Library.

The five Lilong 1 glass discs used to burn information left a large portion of the storage capacity unused.

Seeing that it was almost noon, they hurried to the canteen to eat.

Return to the data center in the afternoon and continue storage and testing.

The first batch of glass discs produced by Long Totem Company totaled 300,000 pieces. Except for some of them sent to the Ministry of Industry and Information Technology, most of the rest were brought over to Time Information.

It is estimated that 29 data storage cabinets can be built, with a total storage capacity of 2.6042 million terabytes. Although this data storage capacity is temporarily sufficient for time information use.

But this is far from enough. According to the long-term plan of Time Information, the total storage capacity of the database must be increased to at least 10 billion terabytes to meet the rapid development needs in the next 5 to 10 years.

While the Dragon Totem Company was busy producing and improving Glass Dragon 1, and building a database for time information.

The Lilong 1 glass disc and supporting equipment have been sent to the Ministry of Industry and Information Technology in Beiping.

The Ministry of Industry and Information Technology pays great attention to the products of Suiren Company, and soon arranged relevant experts and engineers to comprehensively inspect and evaluate Lilong 1 glass discs.

The experts responsible for testing and evaluation, as well as related engineers, were shocked by the powerful performance of Lilong 1 glass disc.

Happy New Year and good luck in the Year of the Ox!
